2 Kings 14:10 - Joseph Benson’s Commentary on the Old and New Testaments

Thou hast indeed smitten Edom A weak, unarmed, undisciplined body of men; and therefore thou thinkest thou canst carry all before thee, and subdue the regular forces of Israel with as much ease. Thy heart hath lifted thee up Here lies the root of all sin; it is in the heart; thence it proceeds, and that must bear the blame. It is not providence, the event, the occasion, whatever it is, that makes men proud, or secure, or discontented, or the like; but it is their own heart that doth it. Thou art proud of the blow thou hast given to Edom, as if that had made thee formidable to all mankind. Glory of this, and tarry at home Content thyself with that glory and success, and let not thy ambition betray thee to thy ruin. For why shouldest thou meddle to thy hurt? As fools often do. Many would have wealth and honour enough, if they did but know when they have enough. That thou shouldest fall, and Judah with thee He warns him of the consequence; that it would be fatal, not to himself only, but to his kingdom, which he ought to protect.
